TRICONEX 3721

The Triconex 3721 module is a highly reliable analog input module for industrial control systems. It can convert analog signals from various sensors (such as temperature, pressure, flow, etc.) into digital signals and transmit them to the upper computer such as PLC or DCS for processing. The module is widely used in safety instrument system (SIS) in petrochemical, electric power, metallurgy and other industries.
